ICD-10 Code F03.92 – Unspecified dementia, unspecified severity, with psychotic disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F03.92 – Unspecified dementia, unspecified severity, with psychotic disturbance
What it is
This code identifies dementia when the type and severity are not specified, but psychotic disturbance is documented. Use it when the record supports dementia with psychosis and does not name a more specific dementia diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Psychotic disturbance may include delusions, hallucinations, or other psychotic symptoms occurring with dementia, and the chart should support both the cognitive disorder and the psychotic features.
When to use this code
Use this code when the provider documents unspecified dementia with psychotic disturbance and no more specific dementia type is available. It also applies when severity is not stated, but the psychotic component is clearly linked to the dementia. Check documentation if the mental status change has another cause.
Do not use for
Do not use this code for dementia without psychotic features or for psychosis that is unrelated to dementia. If a more specific dementia type or severity is documented, code that instead.
Coding tip
Confirm that psychotic disturbance is explicitly associated with dementia in the note before assigning F03.92.
